Get Entities Attached to Cosmetic Thread Example (VBA)

This example shows how to locate all cosmetic thread annotations in the drawing view, obtain the associated entities, and query those entities for their radius values.

'----------------------------------------------------
' Preconditions:
' 1. Open a drawing of a model with a cosmetic thread.
' 2. Select a drawing view of the model with the cosmetic
'    thread.
'
' Postconditions: Displays a message box with the
' radius of the cosmetic thread.
